Simple alpha-(bromomethyl)styrenes can be processed to a variety of 1,1-difluorinated electrophilic building blocks via I(I)/I(III) catalysis. This inexpensive main group catalysis strategy employs p-TolI as an effective organocatalyst when combined with Selectfluor (R) and simple amine center dot HF complexes. Modulating Bronsted acidity enables simultaneous geminal and vicinal difluorination to occur, thereby providing a platform to generate multiply fluorinated scaffolds for further downstream derivatization. The method facilitates access to a tetrafluorinated API candidate for the treatment of amyotrophic lateral sclerosis. Preliminary validation of an enantioselective process is disclosed to access alpha-phenyl-beta-difluoro-gamma-bromo/chloro esters.

The hydrogenation of nitroarenes is one of the most important strategies for the preparation of anilines. However, it is still a great challenge to develop mild and efficient synthetic routes toward aniline synthesis, particularly those employing both non-precious metal catalysts and low-pressure H-2. Herein, we report a highly efficient protocol for the selective hydrogenation of nitroarenes in neutral H2O using H-2(1 atm) over a heterogeneous Zn(0) catalyst under mild conditions. The nitro groups of an array of nitroarenes can be converted into -NH(2)with up to 99% conversions and a selectivity of >99%, even when functionalized with easily reducible substituents, or in the presence of aromatic ketones or styrene. This study might open an avenue for the selective hydrogenation of nitroarenes over a zinc catalyst using 1 atm H-2.

Objective To classify a cohort of depressed adolescents recruited to the UK IMPACT trial, according to trajectories of symptom change. We examined for predictors and compared the data-driven categories of patients with a priori operational definitions of treatment response. Method Secondary data analysis using growth mixture modelling (GMM). Missing data were imputed. Trajectories of self-reported depressive symptoms were plotted using scores taken at six nominal time points over 86 weeks from randomisation in all 465 patients. Results A piecewise GMM categorised patients into two classes with initially similar and subsequently distinct trajectories. Both groups had a significant decline in depressive symptoms over the first 18 weeks. Eighty-four per cent (84.1%, n = 391) of patients were classed as ‘continued-improvers’ with symptoms reducing over the duration of the study. A further class of 15.9% (n = 74) of patients were termed ‘halted-improvers’ with higher baseline depression scores, faster early recovery but no further improvement after 18 weeks. Presence of baseline comorbidity somewhat increased membership to the halted-improvers class (OR = 1.40, CI: 1.00-1.96). By end of study, compared with classes, a clinical remission cut-off score (<= 27) and a symptom reduction score (>= 50%) indexing treatment response misclassified 15% and 31% of cases, respectively. Conclusions A fast reduction in depressive symptoms in the first few weeks of treatment may not indicate a good prognosis. Halted improvement is only seen after 18 weeks of treatment. Longitudinal modelling may improve the precision of revealing differential responses to treatment. Improvement in depressive symptoms may be somewhat better in the year after treatment than previously considered.

On water catalytic aldol reaction catalyzed by polyetheramine (D230) has been developed for easy access to 3-substituted 3-hydroxyindolin-2-ones through the reaction between various substituted isatins and acetophenones/cyclic ketones in high yields under room temperature. Systematic mechanism investigation uncovers the secret for the on water catalytic aldol reaction: comparison of the heterogeneous and homogeneous reaction circumstances with yields of 95 and 20%, respectively, indicates the on-water reaction dominating; interfacial hydrogen bonding between isatin with H2O is tested based on the downfield shift of the C2 and C3’s C-13 NMR signals when water was added to the CDCl3 solution of isatin; Lewis base polyetheramine D230 catalyzes the aldol reaction via the enamine mechanism verified by in situ NMR and ESI-MS analysis.

alpha-Glucosidase inhibition has been considered as an effective strategy for controlling the post-prandial hyperglycemia in diabetic patients. A series of novel isatin-pyrazole hybrids has been rationally designed, synthesized and characterized by different spectroscopic techniques. All of the synthesized compounds were evaluated for their alpha-glucosidase inhibitory potential using in vitro enzymatic assay. The tested compounds have exhibited potent alpha-glucosidase inhibition with IC50 values ranging from 3.26 +/- 0.25 to 32.33 +/- 1.08 mu M. Compound V7, having 3-nitro phenyl ring appended at pyrazole nucleus, has emerged as the most potent inhibitor among the series with an IC50 value of 3.26 +/- 0.25 mu M, which was approximately 146 fold more potent than the clinically used drug acarbose (IC50 = 478.07 +/- 1.53 mu M). Molecular docking studies were carried out to investigate the binding interactions of most active compounds with the active site of the enzyme. Further, in silico predictive pharmacokinetic parameters (ADME) and drug-like properties of the compounds were within the acceptable ranges. In vivo biological evaluations further supplemented the in vitro results.

C-Glycosides are both a common motif in many bioactive natural products and important glycoside mimetics. We demonstrate that activating a hemiacetal with a sulfonyl chloride, followed by treating the resultant glycosyl sulfonate with an enolate results in the stereospecific construction of beta-linked C-glycosides. This reaction tolerates a range of acceptors and donors, including disaccharides. The resulting products can be readily derivatized into C-glycoside analogues of beta-glycoconjugates, including C-disaccharide mimetics.

Polyfunctional pyridines are backbone of numerous natural products and pharmaceutical reactive intermediates. We have developed an iron-catalyzed cyclization reaction between ketoxime carboxylates and nitrones to afford trisubstituted pyridines. Employing this strategy, we have synthesized a number of trisubstituted pyridines with various functional groups in good yields under simple reaction conditions. It is worth mentioning that the nitrones can serve as a novel C1 unit in organic synthesis.

The synthesis, electronic structure, and reactivity of a uranium metallacyclopropene were comprehensively studied. Addition of diphenylacetylene (PhC equivalent to CPh) to the uranium phosphinidene metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U=P-2,4,6-tBu(3)C(6)H(2) (1) yields the stable uranium metallacyclopropene, [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U[eta(2)-C2Ph2] (2). Based on density functional theory (DFT) results the 5f orbital contributions to the bonding within the metallacyclopropene U-(eta(2)-C=C) moiety increases significantly compared to the related Th-IV compound [eta(5)-1,2,4-(Me3C)(3)C5H2](2)Th[eta(2)-C2Ph2], which also results in more covalent bonds between the [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U2+ and [eta(2)-C2Ph2](2-) fragments. Although the thorium and uranium complexes are structurally closely related, different reaction patterns are therefore observed. For example, 2 reacts as a masked synthon for the low-valent uranium(II) metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U-II when reacted with Ph2E2 (E=S, Se), alkynes and a variety of hetero-unsaturated molecules such as imines, ketazine, bipy, nitriles, organic azides, and azo derivatives. In contrast, five-membered metallaheterocycles are accessible when 2 is treated with isothiocyanate, aldehydes, and ketones.

A facile and general synthesis of 2,4,6-triaryl pyrimidines has been developed. It involves a one-pot [2+1+1+1+1] pseudo five-component annulation of one methyl ketone, two aldehydes and two NH4OAc catalyzed by TfOH. One C-C and four C-N bonds are formed during the oxidative annulation process. The reaction shows good tolerance of many important functional groups in air and produces only water as the coproduct, making this methodology a highly versatile alternative to the existing methods for structuring pyrimidine framework.

Metal-directed self-assembly has been applied to prepare supramolecular coordination polygons which adopt tetrahedral (1) or trigonal disklike topologies (2). In the solid state, 2 assembles into a stable halide-metal-organic material (Hal-MOM-2), which catalyzes H2O oxidation under photo- and electrocatalytic conditions, operating with a maximum TON = 78 and TOF = 1.26 s(-1). DFT calculations attribute the activity to a Co-III-oxyl species. This study provides the first account of how Co-II imine based supramolecules can be employed as H2O oxidation catalysts.
